This sounds like a regression from enabling page cache for pages with plug-ins. An assertion fails in debug builds:

ASSERTION FAILED: m_frameCount + 1 == frameCount
/Users/ap/Safari/OpenSource/Source/WebCore/page/Page.cpp(1058) : void WebCore::Page::checkFrameCountConsistency() const
1   0x104e0a79a WebCore::Page::checkFrameCountConsistency() const
2   0x103f59f39 WebCore::Page::frameCount() const
3   0x1045fcfa3 WebCore::HTMLPlugInImageElement::allowedToLoadFrameURL(WTF::String const&)
4   0x104596bb9 WebCore::HTMLEmbedElement::updateWidget(WebCore::PluginCreationOption)
